Perkins 4-154 Rebuild or Repower
 
hi all. it seems ive got a bad head gasket or worse and before i disassemble i would like to weigh the options of a) rebuild the perkins 4154, b) repower with a yanmar, in which i would have to change my transmission and re-pitch my prop ,or c) i am told that if i repower with a cummins , my transmission will mount right up. Any suggestions ? Thanks

The 4-154 is a very good engine, and there are folks around who have parts and rebuild and guarantee them.

The Yanmar's are also good engines...not as robust or long-lived as the Perkins...but very popular.

Seems to me it depends on whether you want to spend $3,000-5,000 for a rebuilt Perkins or $15,000-20,000 (all told) for a new Yanmar or Cummins.

I would at least go as far as removing the head and looking at the condition of the cylinder bores. If they are not scored and you weren't burning a lot of oil and/or experiencing excessive blowby, then rebuild the head and put it back together.

I thought new engines came with a transmision? All you need to do is match the gear ratio and rotation.

thanks for the replies fellow sailors. i have gotten some prices , new head- 1800, head gasket- 450, water pump - 600. rebuild kit for lower end [short block]-2000.add the labor, in and out and to rebuild it will cost around 10,000. labor prices are high up here, 95/hr. havent got a price for cummins yet, not sure which engine is comparable or the yanmar. i am going to remove the head in any case and check out the cylinders . thanks

why not look at machining what you have and doing the rebuild --why go to new head--is it cracked/warped.befouled?? why increase your expenses

if you dont like perkins, send it to me,,,i will readily receive it--shipping is on you, as you didnt want it.....

Cummins 4b3.3 is nearly a straight drop in for a 4-154. Remember though if you repower there will all sorts of bits you will probably replace.

Hi Rockborn, we were faced with a similar dilemma and have just overhauled our Perkins 4154. We are happy went with this route and hope to have many more hours on the original. Spare parts are still readily available , I can recommend Trans Atlantic Diesel for quality of parts and service. Good luck

There is a fellow here on CF that rebuilds 4-154s for much less than $10000. A direct drop in replacement will save you much in labor costs. 4-154 is a great engine.___just my 2 cents worth.____Grant.

Re: Perkins 4-154 Rebuild or Repower
 
Another little note. I have a friend that is a Cummins salesman, and he told me that the small Cummins engines are Japanese engines converted by Cummins. You might be buying a Yanmar,Isuzu,Mitsubishi,etc in disguise. Ask the dealer what the basic block is?___Just a thought.____Grant.

I've a seized 4-154 in my 82 Morgan 416. Would like the rebuild route, but don't have any idea of costs, and removing the engine looks impossible ...is it possible to do a rebuild (partial) still installed.

Not really. You need to be able to remove the oil pan to do an ovhl of a seized Perkins. To bad it's not a tractor then you pull up under a tree and go to town on it.:)

Anybody tried these guys? Seems like a good deal. Might give them a call and discuss it?
